It is possible for a scan to fail to see Probe Response or Beacon frame
under heavy load (e.g., during a parallel-vm.sh test run) since the
dwell time on a chanenl is quite short. Make the test cases using
INTERWORKING_SELECT more robust by trying again if the first attempt
does not find a matching BSS.

The previous check for dl_list_len() or having an entry from the list is
sufficient, but some static analyzers cannot figure out that
dl_list_first() and dl_list_last() will return non-NULL in this type of
cases. Avoid invalid reports by explicitly checking for NULL.

If a 2.4 GHz band AP receives a 20/40 Coexistence management frame from
a connected station with 20/40 BSS Intolerant Channel Report element

Extend the minimal HT 20/40 co-ex support to include dynamic changes
during the lifetime of the BSS. If any STA connects to a 2.4 GHz AP with
40 MHz intolerant bit set then the AP will switch to 20 MHz operating
mode.
If for a period of time specified by OBSS delay factor and OBSS scan
interval AP does not have any information about 40 MHz intolerant STAs,
the BSS is switched from HT20 to HT40 mode.

There could be pending unsolicited event messages on the monitor socket
when the DETACH command is issued. As such, the response may be
something else then OK even if the actual detach operation succeeded.
Try to avoid this be dropping pending messages before issuing the detach
command. As an additional workaround, check the response against FAIL
instead of requiring OK so that the self.attached does not get left to
True incorrectly even if an additional event message were to be
received.

Previously, the frequency conflict was handled only during the
association flow. However, some drivers, e.g., mac80211 based
drivers, will fail an authentication request in case that there
are no available channels for use (as they might be used by
other interfaces), and thus the frequency conflict resolution
is never called.
Fix this by calling frequency conflict resolution during
authentication (SME-in-wpa_supplicant) as well.
In addition, get the shared radio frequency from the wpa_s context in
both the SME-in-driver and SME-in-wpa_supplicant cases and not from the
driver.

The normal scan counter is used to trigger a few normal scans before a
scheduled scan is issued. The reason for doing this is that we get
results faster and some drivers support more SSIDs per normal scan
than during sched scan. After 2 normal scans, we start using
sched_scan. But the problem is that when a connection succeeds, we do
not reset this counter, so we will keep using sched scans.
To fix this, now we reset the counter when we switch to WPA_COMPLETED
state.
